Transmission Fluid Pour the fluid into the filler hole slowly and carefully so you do not spill any. Clean up any spills immediately; it could damage components in the engine compartment. Let the fluid run out until it stops, then reinstall the check bolt and the filler bolt. Make sure to put a new washer on each bolt when reinstalling it. Maintenance Reinstall the under cover, tighten the mounting bolts securely, then put the holding clips back in place. Make sure the under cover is installed under the edge of the front bumper. If Acura MTF is not available, you may use an SAE 0W-20 or 5W-20 viscosity motor oil with the API Certification Seal that says ''FOR GASOLINE ENGINES'' as a temporary replacement. However, motor oil does not contain the proper additives, and continued use can cause stiffer shifting. Replace as soon as it is convenient. The transmission should be drained and refilled with new fluid according to the Maintenance MinderTM (see page 531 ). If you are not sure how to check and add fluid, contact your dealer. 552 2013 TL
